B. Elastic potential to kinetic energy
The elastic potential energy in the slingshot will be transferred to the stone as kinetic energy as the stone is launched.
Answer:
s=62.5m
Explanation:
Use the equation v²=u²+2as, where v is the final velocity, u is the initial velocity, a is the acceleration and s is the distance.
0²=25²+2(-5)s
10s=625
s=62.5m
Answer: yes
Explanation: Assuming a it's moving 20m/s in the west direction and slowing down at a rate of -5m/s² (deceleration), the negative sign would imply the westward direction because -5 west is the same thing as +5 east. So, the boat is moving 20m/s west direction and accelerating at 5m/s² east direction.
Other examples of these are: Cars and and tricycles.
